Baron Talbot of Malahide (or de Malahide) is a title that has been created twice for members of the same family—in 1831 in the Peerage of Ireland as Baron Talbot of Malahide, and in 1856 in the Peerage of the United Kingdom as Baron Talbot de Malahide. While the barony of 1856 became extinct in 1973, the barony of 1831 is extant. The ancestral seat of the family until 1976 was Malahide Castle, close to the village of Malahide, north of Dublin in Ireland.

The first creation, as Baron Talbot of Malahide, in the County of Dublin, was in the Peerage of Ireland in 1831 for Margaret Talbot, née O'Reilly, the widow of Richard Talbot, heir of the ancient Lords of Malahide. She was succeeded by their eldest son, the second Baron. In 1839 he was created Baron Furnival, of Malahide in the County of Dublin, in the Peerage of the United Kingdom. However, this title became extinct on his death while he was succeeded in the Irish barony by his younger brother, the third Baron. The latter was succeeded by his son, the fourth Baron. In 1856 he was created Baron Talbot de Malahide, of Malahide in the County of Dublin, in the Peerage of the United Kingdom, and later held office as a government whip in the Liberal administrations of Lord Palmerston and Lord Russell. When he died the titles passed to his eldest son, the fifth Baron. This line of the family failed on the death in 1948 of the latter's son, the sixth Baron. The peerages were inherited by the late Baron's first cousin, the seventh Baron. He was the son of the Honourable Milo George Talbot, fourth son of the fourth Baron. Lord Talbot de Malahide was a diplomat and notably served as British Ambassador to Laos from 1955 to 1956. However, on his death in 1973 the barony of 1856 became extinct while the Irish peerage passed to his third cousin, the eighth Baron. He was the second son of John Reginald Charles Talbot, grandson of Admiral The Hon. Sir John Talbot, third son of the first Baroness. When he died the title passed to his younger brother, the ninth Baron. The latter was succeeded by his first cousin once removed, the tenth and (as of 2013) present holder of the title.

The 10th and current Baron Talbot of Malahide is the son of Reginald John Arthur Arundell (who in 1945 assumed by Royal license the surname and arms of Arundell), eldest son of Reginald Aloysius Talbot (grandson of the aforementioned Admiral the Hon. Sir John Talbot) and his wife Mabile Mary Arundell, daughter of Hon. Robert Arthur Arundell, fourth son of James Everard Arundell, 9th Baron Arundell of Wardour and Charlotte Stuart Parkin, youngest daughter of Dr. Henry Parkin, RN, Inspector-General of Hospitals and Fleets. Lord Talbot of Malahide also holds the title Hereditary Lord Admiral of Malahide and Adjacent Seas (created by King Edward IV). His wife Patricia Mary, Lady Talbot of Malahide, is a Dame of Malta (SMOM).
